Undersized adapter for workload power demand

A computing device comprising:

• a power port;
• a chipset;
• a controller to:
• determine that a power adapter is attached to the power port, wherein the computing device has a nominal power rating;
• determine that the power adapter has an adapter power rating that is less than the nominal power rating;
• suppress an adapter presence signal to the chipset, wherein the adapter presence signal indicates that the power adapter is attached to the power port of the computing device;
• and
• send an alternative battery presence signal to the chipset to cause the computing device to identify the power adapter as an alternative battery.

A non-transitory computer-readable storage medium comprising instructions that when executed cause a controller of a computing device to:

• determine that a power adapter attached to a power port of a computing device has an adapter power rating that is less than a nominal power rating of the computing device;
• determine that the power adapter has an adapter power rating that meets a workload power demand;
• and
• identify the power adapter as a battery to the computing device to power the computing device.
